Y Specification of Letters Patent. Patented 01611. 19, 1915- Application filed February 25, 1909, Serial- No. 480,001. Renewed-March '5, 1914. Serial No. 822,769.

To all whom it may concern;

Be it known that I, LOUIs F. FLIPsE, a citizen of the United States, and a resident of Sheboygan, county of Sheboygan, and State of Wisconsin, have invented certain new and useful Improvements in Veneer Pads, of which the following is a specifica tion.

The present invention relates to veneer pads, such as may be employed for packing fragile articles for shipment and for other purposes and seeks to provide an improved pad of corrugated wood veneer that is extremely strong and durable and inexpensive to manufacture. v

The invention consists in the features of novelty hereinafter ,set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims. I

The improved article or pad comprises a strip of wood veneer bent to form a series of parallel corrugations that run transversely or at an angle to the grain of the wood, and the side walls of which corrugations are preferably inclined inwardly toward each other. In manufacturing the improved pad, a strip of thin'wood veneer, preferably of one-siXtieth to one-hundredth of an inch in thickness, is employed. Birch,

cotton-wood, maple and other woods can be used. The thin veneer strip, thoroughly dampened so that it can be easily bent without breaking, is corrugated transversely of the grain by bending it around a number of V The forming rods are held forming rods. in parallel series and moved close together to incline the side walls of each corrugation inwardly toward each other at the open.

side thereof.- The strip is then dried while held in this form upon the rods to set the corrugations. A pad thus formed of thin veneer will have the corrugations perma nently set therein and will have greater strength transversely of its plane than a A pad thus formed, while capable of other uses, is admirably adapted for use as a packing pad for bottles and'the like. It is flexible and may be bent around the bottle or like article, is strong, and, at the sametime sufficiently yielding to effectually cushion any blow which might otherwise injureside thereof, pressure or a blow applied to the pad will not flatten out the corrugations. Instead, it will tend to bring the side walls of the corrugations into contact and thereby strengthen or stiffen the same.

1 The drawings illustrate different forms of the invention for various uses. They also illustrate corrugations of different outline.

In the drawings, Figure l is a perspective view of one formof the improved pad, designed for use inpacking glassware, bottles and the like. Fig. 2 is a perspectiveview of the form shown in F 1 with its ends connected to inclose a bottle or other like artlcle. Fig. 3 is a Viewv similar to Fig. 2

illustrating a modified form. Fig. 4: is av perspective view of one end of a mailing tube constructed with the improved pad. Fig. 5 is a view similar to Fig. 4. illustrating amodified form. Fig 6 is a perspective right angles tothe grain of the wood but.

maybe inclinedat an acute angle thereto. The side walls 1 of the corrugations extend transversely of the pad from one of its faces to the otherand the grain of the wood extends through the side walls in the same direction, so that the corrugations act to effectively resist pressureor impact upon the face of the pad. The side walls 1 of each corrugation extend transversely through the pad and are preferably inclined inwardly toward each other at the open side' of the corrugation, so that pressure or a blow upon the face ofthe pad will not tend to flatten out the corrugations and thereby destroy the efiiciency of the pad. The outerrportions ofthe corrugations are preferably semicircular in section to form a series of arches 2 on at least one side of'the pad. As the corrugations or arches are formed of thin wood veneer. and as the side Walls thereof I extendtransversely through the pad, they are strong and practically self-sustaining,

so that they efiectively resist pressure or blows on the pad. As the grain of the wood extends transversely or at substantially right angles to the corrugations it extends through the side walls of the corrugations transverse to the plane of the pad and also extends circumferentially around the arches 2 to thereby increase the strength and effectiveness of the pad. In the form shown in Fig. 3, the outer portions of corrugations on both sides of the pad are semi-circular in section. In the form shown in Figs. 1 and 2, the outer portions 3 of the corrugations on the one face of the pad are flattened, as shown, and the corners 4 of these corrugations are arranged closely adjacent one another, so that the pad will have a substantially smooth outer surface. lVhen the pad is thus formed, pressure upon it will bring the corners 4c into contact and thereby stiffen the corrugations and increase its power to resist pressure or blows. These corners are, however, rounded so that the fiber of the wood veneer is not broken.

The pads that aredesigned .for bottles, glassware and the like, are shipped to the userin the flat form shown in Fig. 1. This pad as a whole is flexible and can be readily bent by the user around the article to be pro-.

tected. By forming the corrugations with the open sides thereof narrower than the closed sides, and by forming them of wood veneer which has considerable stiffness and strength,the corrugations can be interlocked, as shown at 5 in Figs. 2 and 3, to firmly unite the ends of the pad to inclose the articles. That is to say, corrugations of a wood veneer strip, though quite stifl and adapted to resist blows, are sufliciently resilient and yielding to permit the corrugations at one end of the pad to be forced transversely between the corrugations at the opposite end of the pad and interlock therewith'and form a strong joint between the ends of the pad without the use of any par- The forms shown in Figs. 1, 2 and 3, can, therefore, be cheaply shipped in flat condition to the user who can easily and readily unite the ends of the pads to receive the bottles or the like. The

pads shown in Figs. 1, 2 and 3 may be employed in'flat form for packing flat articles and may, if desired, be provided on one side with a covering sheet of fiexible'paper.

The forms shown in Figs. 4 and 5 are designed as mailing tubes. In the tube shown in Fig. 1', the arch-like or semi-circular corrugations 2 are on the outer face of the pad and the flat corrugations 3 are arranged upon the inner face of the pad with their corners 4 in contact, or substantially so, so that the mailing tube is provided with a substantially smooth, cylindrical inner surface and drawings, papers or the like can be readily inserted into the tube. In the form shown in Fig. 5, the corrugations are provided with flattened, outer faces 3", as well as the flat inner facesS'. ing tubes are preferably made up complete by the manufacturer and may have a coverwith stout casings of paper board or thin veneer, these mailing tubes have considerable stiffness and rigidity. The'covering 6 comprises a veneer strip extending spirally around the tube and extending across and cemented to the corrugations, with the grain of the covering strip at an angle to the corrugations, whereby added strength is given to the tube. I

In the form shown in Fig. 6, the corrugations of the pad on both sides thereof are formed with flat faces 3 and both sides of the pad are covered with sheets 6 of thin veener. This construction is intended as a substitute for paste-board and wood in the manufacture of boxes and cartons. The grain of the veneer covering 6 extends transversely to the corrugations, either at right angles as shown, or at an acute angle, and the construction is very strong, of light weight and is inexpensive.

All forms of the improved pad are manufactured by bending a dampened strip of thin veneer transversely of the grain around a series of forming rods 7, as shown in Fig. 7 These forming rods should, of course, be of different cross section when corrugations of different outlines are to be formed. The forming rods are held in parallel relation and are moved together so as to incline the side walls 2 of the corrugations toward each other. The strip is then dried while held in this form upon the rods to set the corrugations. In a pad thus formed, the corrugations will be permanently set therein and the pad will be very strong, and, at the same time, is flexible as a whole so that it can be readily bent around the articles to be protected, as in the forms shown in Figs. 2 and 3, which are particularly designed for packing bottles or like glassware.

The mailing tubes shown in Figs. a and 5 and the flat construction shown in Fig. 6, are provided with stiffening covering sheets of paste-board or thin veneer and are comparatively rigid.

It is obvious that the details set forth may be varied without departure from the essentials of the invention.
